This is a NEED to know insulin chart.
Rapid (Humalog ) Acts within 15 Min. Peaks in 1 hour.
Short acting (Humulin R) Acts within 30-60 min. Peaks in 2-4 hours.
Intermediate (NPH) Acts within 1-3 hours. Peaks in 6-12 hours.
Long acting (glargine, Lantus) Acts in 1 hour. NO PEAK
Remind patient’s to change insulin injection sites daily because over time, the same location will not absorb the insulin as correctly.
Also usually a good idea to choose an assessing the patient’s blood glucose answer before an implementation answer choice on the NCLEX.
